` IMPROVE!) WATER-ELRVATOR AND cARRIeR.l

l The ScheduleA referred to in these Letters Patent and making part of the same f To all whom item3/concern Beit known that we,`ARoH1BALD A. MoPHnTERs and ROBERT .1. MoPHnE'rERs, of Arbor Hill, in `the l county of Allgu'sta and State of Virginia, have inventeda new and improved Water-Elevatorand Carl. rier; and we do hereby declare that the following is This invention relates to elevating material from mines,` wells, or any placewhence it is to be raised and carried. r t The inventlonconsists in an automaticdevice for A disengaging from thewindlass that carries thebucketropefhe4 pawl that prevents said wiudlass from rotating, in order to" allow the bucket to descend botlr for iilling` and. emptying; in combination, an automatic device for enabling the bucket as it is raised,"both after being illed andaft'er being-emptied, to release the' hooks which `attach the carrier to the bulkheads at way `on which the carrier moves.

' In the drawingse y Ais the carrier, consisting of-a box` mounted on wheelsa a, which run'on au inclined railway, B, elevated over the mouth of the pit;

C is the ywindlass, which carries the bucket rope.

The windlass is mounted crosslwise of the carrier, having a ratchet, c, at one end.`

D is a pawl, `hung to the inside of the carrier at a point'where its lower end may engage with the ratchet the Aupper and lower ends of the inclined'elevated rail m is a spring, which tends to `keep the `paw] constantly engaged with the ratchet.

`E E' are rods pivoted to the pawl D, one above and the other below its fulcrum,'and extending, `one through the forward end of the carrier and the other through its rear end, andprojectiug outside these ends y so far that, when the carrier runs down to the bulkhead F at the end of'the frame that sustains rthe elevated railway, 4the bulkhead strikes the rod E', and forces it back, and thus disengages the pawl D from the ratchet c, so that Vthewindlass is left free to be. revolved by the weight of the bucket G descending into the well, mine, or other excavation, wh0se mouth is supposed to be immediately in front Qt' the end H of the sustaining-'frame The bucket, havingy been filled, is raised. by rotating the windlass t', placed within convenient reaching dis-v tance across the end I lof the sustaining-frame, to

which `windlass is attached the opposite extremity of the bucket-rope b.

K is a plate,'attached at its extremities to the lower ends of bars L' k, provided with upwardlypressing springs, which slide in guide-ways on the inner sides of -the two ends ofthe carrier Ay, opposite ,each other, so that the plate K extends vbeneath the carrier lengthwise, and has an orifice for the bucket-chain d to pass througlnbut too small to admit the bucket.

Hooks e e project outwardffrom the bars k, one of which hooks catches over the top of the bulkhead F wheuvthe carrier runs down to the latter.

As soon as the bucket, during its ascent, strikes the plate K, it throws the latterup, Areleasing the hook e from the bulkhead F. The rope Bthereupon draws the carrier up the inclined railway B, bearing the bucket held against its under side, until the front end ofthe carrier strikes the upper bulkhead L, when the upper hookl e catches over the bulkhead and holds the carrier fast. At the same time the projecting end ot' the barE strikes the bulkhead and throws the upper end of thepawl D backward, so as to disengage it from ther-ratchet c and allow the windlass C to be rotated by theweightof the full bucket as the latter descends to be emptied.

On raising the cniptybucket, as soon as it strikes `the plate K it releases the hook e, from the bulkhead L, and allows the carrier to run by its own gravity downlhe railway till it strikes the bulkhead F, when the other hook e catches over the latter, and the bar E disengages the windlass, again allowing the bucket to descend into the pit, as before described. l

Having thus described our invention,

What we claim as new,and desire to secure by Let-4 lters Patent, is-

The combination of the pawl D, rods E E', wndlass 0prov`ided with-the ratchet c, plate K, rods klapro-y vided with' the hooks e, and the bulkheads, all constructedand arranged to operate as described ARCHIBALD A. MCPHEE/BEES. -ROBERT l. 'MCPHEETERS `Witnesses: t
